How do I install reflex?
- Find the launch command. The README says how the server starts (npx, uvx, docker or a remote URL) and which API keys it needs.
https://github.com/reflex-search/reflex
- Add it to Claude Code. Replace the part after -- with the command from the README. Remote servers use --transport http with a URL.
